News: Explosive or quiet?
Heliotime.org is a software for discovering when the Sun was active or quiet by a timeline of peaks and lows spanning over 20 years of solar activity. By clicking on any point in the time axis you will get a preview of the sun at the date you chose. Should you wish to look at the image in more detail, heliotime leads you to helioviewer.org, the NASA software for exploring solar activity in many wavelengths and high resolution. The tool is interesting for lays, too. Check it out! Heliotime started as a student project at the Institute for Data Science and was used for an interactive installation representing heliophysics in Switzerland at the Science Museum London Lates on November 28.
